I think regular fluid and filter changes are sufficient. However if I were inclined to do a flush, I’d start on a warm truck, start it with a return line disconnected, and add fluid through the dipstick until it flowed clean. Then drop the pan and change filters, but I’m a bit OCD about regular maintenance so I revert to my first sentence.

I have a problem with blowing out the cooler the way he did. First is moisture, I drain my compressor tank pretty regular, and then it goes thru a dryer before it goes to the hose. Even with that, in these humid summer months I can trigger my air gun at times and see the moisture come out. Second, normal shop air is over 100 psi. If you want to do what the video shows, add another dryer/regulator and don't blow much over 3-5 psi thru the cooler.
Also why wouldn't you install a new bypass TP filter? You have it open, put a new element in there.

IMO after watching them both, I like the one posted by

better. Never thought of the 3/4" tubing idea, that'll safely get more out than just a pan drop.

you can not get the transmission warm enough while sitting in a driveway doing a flush for the cooler circuit to remain fully open

that why these need the heated flush or the direct filter tube refill trick ( I think Bismic posted a link )

the cooler circuit system control is not able to be manually bypassed or manipulated with electronics

i wish it was that easy

I know that. I was just wondering where the thermostat is in the system. And the tube trick in the system, how does it get the fluid that the thermostat has blocked while it’s closed. I’m just trying to figure out how this makes for a complete system flush.
